Wow Jenni,
I'm only through Chapter one and I feel like every sentence Im find myself thinking that words you typed are the exact ones that I think day in and day out!
I have a theory about squares. It may sound super strange but I believe that God has one persons set aside for you, your square. and that often times there are people that are meant to be in your life that fit and that are there for specific reasons -- whether it be to teach you something about yourself or about love in general -- and that these people can be triangles. or whatever else it is. because a triangle fits inside a square too, but not perfectly. only a square fits inside a square perfectly.
hahah sorry for all of this random babbling! i just can relate on so many levels :) and your story is just beautiful! I'm so excited to read more :D
